DTC P2405: Notes
DETECTION CONDITION AND POSSIBLE CAUSE (DTC P2405)
| DTC P2405 |
EVAP system leak detection pump sense circuit low input |
| DETECTION CONDITION |
- The PCM monitors pump load current (EVAP line pressure), while evaporative leak monitor is operating. If the current is lower than the specification while the PCM obtains the reference current value, the PCM determines EVAP system leak detection pump orifice has a malfunction.
Diagnostic support note
- This is a intermittent monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- The DTC is stored in the PCM memory.
